Ovary - Corpus Luteum

(Stain - Haematoxylin Eosin) Histology image shows the ovary in overview, the cortex and medulla of the ovary can be clearly seen.

corpus luteum (yellow body) theca lutein cells and granulosa lutein cells. These cells work together in the production of ovarian hormones that support the initial pregnancy.

corpus albicans (white body) lack of implantation and associated hCG will lead to this structure not producing hormones.

Atretic follicles are the degenerating follicles from various developmental stages that did not form the ovulating follicle and do not form the corpus luteum.

Connective Tissue

  • fills most of the original follicular fluid-filled space.

Granulosa Lutein Cells

  • the lighter stained cells.
  • derived from the granulosa cells of the original follicle.
  • contain aromatase enzyme.
  • produce estrogen and progesterone from the androgens produced by the theca lutein cells.


Theca Lutein Cells

  • the darker stained cells.
  • derived from the theca interna of the original follicle.
  • lack microvilli on the surface.
  • lack the aromatase enzyme.
  • produce androgens for the granulosa lutein cells to convert.
